Seems very strange,
It does not seem to be a configuration issue (unless there were someone stopping the project exactly at that time). Theoretically if it works for one work-unit it should work for all the others.
The intermittence of the problem make me think that it could be a performance problem server-side. I will look into that soon.

I checked the CPU time on the server and it does not seem a performance problem.
I also quickly checked the logs of the feeder and scheduler, but in general they didn't give any error.
Furthermore, from the workunit list that other users seem to correctly receive workunits.
I will check the issue in more details tomorrow.

This computer (from Boboviz) is a 6 core, with already 30 in progress, got nothing because hits the limit

I've seen the limit and now i have 30 wu
But i have "0 unit" message also when i have NO wu in my pcs...
And after 1 or 2 h. my computers restart to download.
Is there a "time limit" for download (only x wu in 24 h, for example), like ralph@home??

IMHO
-stay with the current limits while in this alpha phase
-do not increase the wu length until we have an application that a) validates correctly if checkpointed b) correctly acts if suspended or resumed

We just updated the application, and deprecated the old one.
The new version should hopefully fix the problems we were having with checkpoints and suspensions.
After a short period of testing we will increase the workunit length (I planned this for tomorrow).

It's quite frustrating.
In the last 24h i've downloaded 20 or 30 wus with 8 core free...In other projects alpha/beta in witch i partecipate (ralph, albert) the daily limit of wu get this message: "You have reached the daily quota of wus".
I try, also, to force the download with a script (scheduled every 5 minutes), without results
